Which of the following best describes the allowed disconnecting means for fixed appliances under NEC rules when not over 300 VA?

• A. Branch-circuit breaker
• B. Attachment plug cap
• C. Separate disconnect switch
• D. All of these

Answer: (D)

For fixed appliances that are 300 VA or less, the NEC allows several ways to provide a disconnecting means, so you’re not limited to a single type. The disconnect simply has to be readily accessible and, for cord-and-plug-connected appliances, the means can be the plug itself if you can unplug it easily and see the appliance. That means the power can be shut off by the branch-circuit breaker serving the circuit, by unplugging the appliance’s plug (attachment plug cap), or by a separate disconnect switch mounted near the appliance. All of these options are permitted, which is why “All of these” is the correct choice. This flexibility helps ensure quick, safe shutdown for maintenance or emergencies without requiring a dedicated disconnect for every small fixed appliance.
